BEARING FOR GRAIN SEPARATORS.

Application filed February 5, 1925, Serial No. 7,086. Renewed April 28, 1927.

rfhis invention has reference more particuarljv to thrashinn` machines. and aims to provide a novel term oil' bearing` to be employed in connection with the supporting shafts oi' the movable elements oil thc ma.- chine.

rlfhe primary object oi' the invention is to provide a bearing' especially adapted il'or use in connection with adjustable operating` rods. whereby the throw ot the rods will not in any waji7 atleet the bearing or the movement oi the supporting;v shaft operating through the bearing.

Another important object oiE the invention is to provide a self adjusting' hearing, the construe-tion thereot beingsuch as to reduce wear and 'friction between the movable elements thereof, to the minimum.

With the foregoing' and other objects in view which will appear as the description proceeds, the invention resides in the comhination and arrangement of parts an d in the details et construction hereinafter described and claimed, it being understood that changes in the precise embodiment ot the invention herein disclosed, may be made Within the scope of what is claimed, without departing- 'from the spirit of the invention.

Referring to the drawings:

Figure l is a ragmental elevational view illustrating the rear end of a thrashing machine.

Figure 2 is a sectional view taken on line 2-2 of Figure 3, and illustrating the sett-adjusting bearings.

Figure 3 is a plan view of the bearing, the cover thereof being removed.

Figure l is a sectional View taken on line 4-4 of Figure 3. Y Y

Figure 5 is a sectional fview taken on line 5-5 of Figure 2.

Referring to the drawings in detail7 the 'trame of the machine is indicated generally b v the reference character 5, and as shown. is supported by the wheels 6 mounted on the axle 7 in the usual and well known manner.

rlhe uppermost straw rack ot the machine is indicated by the reference lcharacter 8 and is operated by means of the rod 9 that has connection with the vertical arm 10 which is pivotally supported at 11.

Connected with the arm 10 at 12 is a rod 13 that extends rearwardly and has pivotal connection with the arm 14 which is mounted on the shaft 15. The reference character 16 `irulicates a rod which has connection with the lower end oi the arm ist ai l?, which rod connects `with a movable pan at to more the same/7 the movable pan liaviner suitable shalts operating; in the hearings 19.

Power is ln'aiisinitted to the arm l() through the .rod 2() which has adjustable connection with tl e arm l() through the medium ot the pin 2l and opei'iings 522. whereby the rod Q0 may he moved verticali;7 to adjust the throw ot the arm l0. A rod indicated at 23 is pivotally connected to the arm l() at 2li. and has connection with the pan at 2G.

The bearing' member forming the important fea-ture oi the invention comprises a sectional housing including the lower seetion 27 and the upper section 28, the lower section being` supplied with a wear plate 9.9 on which the roller bearings 30 move. An elongated roller cage is indicated bv the reference character 31 and is adapted te reciprocate within the lower section under the action oit the shoe or shaft siumorting member to be hereinafter more fully described. l

Positioned within the lower section oit the housing are lateral plates 32 which are formed with cut out portions dehning` shoulders that are disposed adjacent to the ends et the housing: so that movement ot the cage will be restricted by the engagement oi? the cage with the shoulders 33 at the ends of its strokes.

The sections oi the housing are i'ormcd with cut out portions 34 that deiine an elongated opening* 35, when the sections are brought together, which elongated opening accommodates the supporting sha'tt that eX- tends into the housing and allows the supporting shaft to reciprocate or move loniritudinally of the housing` to accomplish its purpose.

Operating' in the housing and supporting' the shaft, is a shoe 36 which is termed with an opening 37 to accommodate the shalt, the shoe being' relatively wide and adapted to rest directly on the rollers 30 te move thereover. In order that the housingwill be dust-proof7 a plate 38 is provided, which. plate is formed with an opening to accommodate the shaft that extends into the bearing, the plate being especially designed for closing the elongated opening 35. The upper edge et the plate 38 is held into contact llO with the housing by means of the angular plate 39 Which holds the plate against lateral movement but 'permits of movement yof the plate longitudinally of the housing.

From the foregoing it Will be obvious that the housing may be `*filled with oil to the end that friction between the shaft and its bearing will be reduced to the minimum and that the bearingv Will compensate for the variation in the movement of the member supported thereby, eliminating the necessity of making an adjustment of the bearV ing when an adjustment of the operating rods has been made to lchangeV the ythrow of the pans or racks operated thereby.

I claim 1. A bearing for reciprocating shafts comprising an elongated housing having an elongated opening in one Wall thereof, av roller cage Within the housing, rollers Within the cage, ashoe supported on the rollers,;-;-'2

a shaft extending through the Velongated opening and positioned Within the shoe kto move therewith, means disposed adjacent to the ends of the housing for restricting movementv of the rollers and cage, and a plate` Y movable with the shaft for closing the elon-4 gated opening. f

2. A bearing for reciprocating shafts of separators, including an elongated housing having an elongated opening in one Wall thereof, a roller cage Within the'housing, rollers Within the cage, a shoe adapted to operate over the rollers,v a` shaft extending through the opening and having connection with the shoe to move therewith, and means carried by the shaft for normally Closing the elongated opening. y

I claim the foregoing Y Intestimony that as my own, I have hereto affixed my signa ture.
